Filter by:Aspiration of gastric contents can be a serious anesthetic related complication. Gastric antral sonography prior to anesthesia may have a role in identifying pediatric patients at risk of aspiration. The investigator examined the relationship between sonographic antral area and endoscopically suctioned gastric volumes infants.
One of religious duties for all healthy adult Muslims is fasting during Ramadan, the ninth month of Islamic lunar calendar. In this month, Ramadan observance fasted (no food and drink) from dawn to dusk. Studies demonstrated daytime fasting may pose a positive significant effect on metabolic health. Thus, this present study aimed to determine the effect of Ramadan fasting on body composition, metabolic profile, serum leptin and adiponectin levels in healthy men.
The purpose of this study is to compare the gastric volume in pediatric patients who followed preoperative fasting guideline using ultrasound.
The primary aim of this study is to examine the effect of acute ingestion of fructose on serum FGF21 levels. Subjects in this study will be lean volunteers and individuals with metabolic syndrome.
Carbon-12 and carbon-13 are naturally-occurring isotopes that are found in exhaled breath. Investigators have proved that the 13CO2/12CO2 breath delta value (BDV) changes in subjects who were in negative energy balance then fed a positive energy balance meal. Measuring one liter of exhaled breath daily may be a more convenient way to measure negative or positive energy balance in patients receiving intravenous nutrition.
Anesthesiologists try to avoid complications with significant peri -operative morbidity and mortality such as bronchoaspiration in patients requiring a surgical procedure under anesthesia. Currently, this is achieved based on experts recommendations from the American Society of Anesthesiologists. However, there are tools like ultrasound that allow assessment of gastric content and volume. This tool allows to individualize each patient and base the decisions objectively. The investigators will assess gastric content and volume by ultrasound in patients who have fasted and require surgery at two University Hospitals.
This study compares differences in hemodynamic ve ECG parameters of patients undergoing urological or orthopedic surgery under spinal anesthesia. First group will comprise of patients undergoing surgery in the morning hours; thus with a standard fasting duration (8 hours), and the second group will comprise of patients undergoing surgery afternoon; thus having a prolonged fasting duration (>12 hours).
Ramadan Fasting has multiple effects on the variation of hematological and biochemical parameters.
The aim of this trial is a first evaluation of the effectiveness of intermittent fasting as a supplementary therapy in patients with CRPC or hormone-sensitive prostate cancer with high metastatic load (1≥ visceral and ≥4 osseous metastases) in respect to quality of life, reduction of side effects and possible reduction in tumor progression.
Background and Aims: The "5:2 diet", a form of intermittent energy restriction, has been popularized in Europe and USA. The rationale behind this approach is that two days of dieting is potentially more achievable, yet long enough to reduce overall weekly energy intake. However, this specific approach is lacking in evidence. Therefore, we are keen to investigate the effectiveness of this form of intermittent energy restriction compared with a control intervention (providing dietary and exercise advice only), in overweight, Chinese subjects, for an intervention period of 12 weeks. Design and Methods: This will be a randomized controlled trial, with 15 subjects in each arm, for an intervention period of 12 weeks. Subjects randomized to the treatment group will take three packets of a meal replacement product (Optifast®) per day during two consecutive fasting days, and take a healthy balanced diet that meet estimated energy requirements for the remaining five days. Subjects randomized to the control group will be given general diet advice and allowed to eat ad libitum throughout the study period. Measurements and laboratory tests will be done at baseline, 4 weeks and 12 weeks. Adherence to the dietary interventions will be assessed at 4 weeks and 12 weeks using 7-day food diaries. Significance: This will be the first study looking at an Asian population and will serve as a pilot towards a larger randomized trial. If this approach is found to be safe, effective and easier to adhere compared to the traditional continuous energy restriction, then it will be a very valuable option in the treatment of obesity, which has become an increasing problem globally including Singapore.
